IMPLEMENT l-'OR EXTRACTING CARTRIDGE-SHELLS.

""1 `SIEEGIFIGA'IION forming part of Letters Patent No. 235,444, dated December 14, 1880.

i Application filed August 18, 1S8 0. (Model.)

11b all whom t may, concern: i f Be itrknown that I, JAMES F. MARVIN, of ,{Fort McDowell, in the Territory ot Arizona, i ,have invented a new and Improved Implement i SzffonExtracting Cartridge-Shells, of which the following is a specification. `flt frequently occurs that the flanged heads "of: cartridge-shells pull off and the. shells are left in the barrel, from which it is difficult to fremove thleri. This is specially liable to oc- `curwith cartridges that have been extracted `several times. l M The object of my invention is to furnish a `"dejgice by which such headless shells can be readily extracted; and the invention consists Vina slotted tube tlanged at one end and proivitled'with an expansion-pin for spreading the be after its insertion in the cartridge. The tractor is applied by insertion in the shell d expanded by closing the breech of the gun, that when the breechis again opened the i shell is drawn out. In the accompanying drawings,forming part Iof thisspecication, Figure l is a perspective view ot my improved device, and Fig. 2 is a longitudinal sect-ion of 'the same as applied to tlcartridge.

Similar letters of reference indicate corresponding parts.

A isatube', preferably of steel, ot a diameer for entering a cartridge=shell snugly, and formed with a flange at one end, as at a. This ube is slotted lengthwise from near the flange a) to the opposite end, there'being two or more i of such slots; and thegouter end of the tube wywhich is divided by the slots is formed tapering, as shown, so that it may readily enter the cartridge. The surface of the tube behind the tapered end is recessed to form shoulders or projections, as at b, which will give a better hold upon the cartridge; but these are not essential.

The tube is tted with a loose pin, c, which7 ifdesired, may be retained by a screw entering a longitudinal slot in the pin, as at d, so that the pin may slide lengthwise. The aperture of the tube is tapered7 the larger' portion being at the flanged end; or the pin c may be tapering, so that the tube shall be expanded when the pin is forced inward.

In using the device it is inserted into the headless shell in the barrel and the breech closed,which will force pin ein and expand the tube A, so that when the breech is again opened-the usual cartridge-extractor takes behindthe flan ge o and draws the tube and shell out together.

The tube can -`be.v released from the shell by driving pin c outward to loosen the tube. This may be done by inserting a separate pin, or the pin c may be made of sufticient length to extend through the cartridge, as shown.

This extracting device is simple and ett'ective, and will save the trouble heretofore experienced in removing headless shells from guns.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A cartridge-extractor consisting ot the tapered slotted tube having flange a, the shoulders b, and expansion-pin c, substantially as shown and described.
